Check our tutorial section for the pandora tutorial (if your buddy has a homebrewed psp you'll need to borrow it to create the battery) or if your completely stuck with no friends that can lend a homebrewed psp then your next option would be either purchasing the datel tool battery or hard modding your battery. We have a tutorial to hard mod the battery with a switch so that you can switch from normal to service mode and back again.
